Application February 19, 1951, Serial No. 211,729

10 Claims. (Cl. 2--97) My present invention relates to an improvedinsulating material of the type especially adapted for use in clothing,bed coverings, sleeping bags and the like, where as in extreme climatesit is imperative to retain warmth while permitting body respiration.

This application is a continuation in part of my application, Serial No.687,811, filed August 2, 1946, now abandoned. Y

Experience has shown that heavy weight of cloth or fabric does notresult in a high rate of heat retention and further such garments as arenow available are bulky and cumbersome and do not permit freedom ofmovement of the wearer.

It is therefor my principal objective to oler a cloth for clothing andthe like made up of two layers of lightweight material with the innerside of the outer layer overlaid with sections of heat reflectingmaterial so arranged as to permit air movement therethrough to permitrespiration of the body while retaining body heat.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention according to the best mode Ihave thus far devised but it will be understood that various changes andalterations may be made in the exemplified structure within the scope ofthe appended claims.

In the drawings:

Figure 1 is a front view of a jacket embodying the construction of myinvention;

yFigure 2 is a plan view showing the sections overlying one layer ofmaterial;

Figure 3 is a detail view showing partial rows of sections to illustratethe overlapping arrangement;

Figure 4 is a detail view showing spaced sections of reilectivematerial; and

Figure 5 is a sectional view at line 5 5 of Figure 3.

Referring now to the drawings wherein I have illustrated the presentpreferred embodiment of my invention I have shown the construction as`applied to a jacket 2 having sleeves 4 and 6 and a collar 8, all ofconventional design and construction.

The material of the jacket consists in an outer layer of fabric and aninner layer of fabric 12, of suitable lightweight cloth as desired whichmay be treated or processed for waterproofing as appears desirable.

On the inner surface of the outer layer 10 I secure pieces or sectionsof heat reflecting material 14 which may be metal foil such as aluminum,lead or chromium, or other suitable metallic foil which possessesflexibility and heat reflecting characteristics. The foil should bepolished to most eectively reflect the body heat of the wearer and thesections may be of various sizes and shapes.

In this embodiment I have shown the sections as rectangular and arrangedin rows 16, the ends of adjoining sections overlapping as at 18 and Iuse a series of rows, the lower edges of the sections of each upper rowoverlapping the upper edges of the lower row as at 20.

The sections of the rows and the series of rows are stitched to thefabric 10 as at 22, the stitches running from diagonally opposed cornersof the overlapping sections and through the centers thereof. In thismanner each corner of each section is secured and the four edges of thesections are not secured so that air movement is permitted in thedirections indicated by the arrows. For use in moderately cold weatherthe spaced apart sec- ICC tions as illustrated in Figure 4 give a moreflexible shield means with greater porosity.

In other words, air may pass under each section along two edges, andover each section along the other two edges. By overlapping thesections, a solid surface heat reiiecting body is interposed between theinner and outer fabrics and the heat normally generated and given off bythe body will be reflected back by the overlapping foil sections to makeoptimum use of such body heat to maintain normal body temperatures.

It has also been discovered that lighter color in the foil sections isconducive to a minimum retention of heat by the sections and it ispossible that other material than foil having similar characteristicsmay well be employed. In addition, suitable material sections may besprayed or otherwise coated with metal to obtain heat reflectingqualities.

From the above description it will be apparent that the material of myinvention will aord a highly reective surface which may be used inlightweight fabric layers to provide lightweight clothing for use evenin extreme conditions as found in Arctic regions, and the loss of heatthrough such a garment and the consequent suffering from cold will belower than in any known material. The sections 14 may be square, asshown in Figures 2 and 4, or may be elongated, as shown in Figure 3.Their edges may run horizontally and vertically, or may run diagonally,as shown in Figure 2. In Figure 3 the overlapped vertical edges arestaggered.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:
